This application is a 371 of PCT/EP00/09904 filed Oct. 9, 1999.

The present invention relates to new 3-pyrroloimidazole derivatives, to pharmaceutical compositions comprising them, to the preparation and use thereof, especially as tumour- and cancer-lysing and more especially as antibiotic, very especially antibacterial, medicaments.

Cancer and tumour diseases are among civilisation's problematic clinical entities. In many cases, the tumour tissue has to be surgically removed and/or treated by chemotherapy. Long-term patient survival is, however, very uncertain. Moreover, chemotherapy and surgical treatment frequently involve pain and other problems for the cancer patient. The provision of new, complementary medicaments for the treatment of tumour and cancer diseases is, therefore, of great interest. Also, it can be assumed, in the light of the general increase in the formation of resistance in micro-organisms and bacteria, that there exists a need for new and similarly active, or even more active, antibiotics.

The problem of the present invention was accordingly to provide new active ingredients having improved and/or complementary action in the prophylaxis and/or therapy of cancer and tumours and/or especially strong antibiotic, more especially antibacterial, activity in the prophylaxis and/or combating/therapy of infections by micro-organisms.

The compounds according to the invention have a high level of activity, especially in cancer and tumour prophylaxis and therapy. That activity allows the active ingredients and pharmaceutical compositions according to the invention to be used as chemotherapeutic agents in human and veterinary medicine.

The term “chemotherapeutic agents” is a broad term encompassing substances having a (substantially) selectively damaging action on tumour cells and pathogens. The terms cytostatic agents and antibiotics are also widely used.

The antibiotic activity of the compounds and active ingredients according to the invention and of pharmaceutical compositions comprising them is especially pronounced. It will be clear that the term “antibiotic” is to be understood in its widest sense and encompasses, for example, antibacterial and antimycotic and/or antifungal action (including action against yeasts).

The compounds or pharmaceutical compositions according to the invention can be used locally or systemically. Systemic administration is understood to mean, for example, intravenous, intrapleural, intraperitoneal, rectal or oral administration or irrigation of body cavities and the urinary bladder. Local administration is understood to mean, for example, subcutaneous, intracutaneous, intratumoral or peritumoral administration, for example in the form of injection solutions, injection suspensions, creams, lotions, gels and ointments.

The life of tumour cells in vitro is significantly shortened by the active ingredients according to the invention compared to controls.

On systemic and local administration, the active ingredients according to the invention have a dose-dependent tumour-lysing action and an especially pronounced antibiotic action. When used therapeutically, the daily dose of active ingredients according to the invention is of the order of from 0.1 to 100 mg/kg of bodyweight, preferably from 2 to 40 mg/kg of bodyweight. In individual cases, the dosage may be higher or lower than that mentioned above.

The active ingredients according to the invention can be used in known manner—depending upon the individual clinical entity—in a formulation, for example patches, ointments, pastes, gels, creams, soluble powders, lotions, emulsions, sprays, powders, suspensions, suppositories and injection solutions.

The active ingredients according to the invention can be formulated, for example, as injection solutions, by dissolving them, where appropriate with the aid of solubilisers, in dilute physiologically acceptable bases and by being brought into an injectable form having a pH of from 6 to 8, especially from 6.9 to 7.5, by the addition of physiologically acceptable acids.

Examples of physiologically acceptable bases are hydroxides, hydrogen carbonates, carbonates of alkali and alkaline-earth metals, especially of potassium, sodium and calcium.

The compounds according to the invention are prepared in a manner customary per se, for example in accordance with van Leussen et al., J. Org. Chem., 42, 1977, 1153-1159.

By way of example, a general procedure for the synthesis of 1,5-disubstituted imidazole derivatives (Examples 1-2) is described below:

6 mmol of amine and 6 mmol of aldehyde are pre-condensed in 3 ml of dichloromethane overnight to form the Schiff's base, the dichloromethane is drawn off and 3 ml of methanol are added to the residue. To the resulting suspension there are added 6 mmol of solid TOSMIC and 1 equivalent of base and the mixture is boiled under reflux at 80° C. for four hours. The solvent is drawn off and the crude product is purified by means of preparative HPLC.

Growth-inhibiting, Cytotoxic and Antibiotic Properties

Assay 1

Measurement of cell growth by determination of the activity of the intracellular enzyme acid phosphatase. The added substrate p-nitrophenyl phosphate is converted by acid phosphatase into p-nitrophenol, which absorbs light at 405 nm, the intensity of the yellow coloration being proportional to the number of cells. Incubation of the cell lines HEPG-2 and A549 together with the substance (0.1-100 μM) was carried out for 48 h and 96 h at 37° C. and 5% CO₂.

Assay 2

Measurement of Cytotoxicity by Quantitative determination of the enzyme lactate dehydrogenase (LDH), a stable cytosolic enzyme that is released into the medium on lysis of the cell. Released LDH is measured by means of a coupled enzyme assay wherein a tetrazolium salt is converted into a red formazan product which can be detected at 490 nm, the amount of colour generated being proportional to the number of lysed cells. Incubation of the cell line HEPG2 and A549 together with the substance (0.1-100 μM) was carried out for 24 h at 37° C. and 5% CO₂.

Inhibition Test

Culture media used: Müller-Hinton broth Caso agar plates

Test method: Microdilution assay

The test organisms are cultured overnight in Müiller-Honton broth at 35° C. +/−2° C. The suspension of organisms is centrifuged (5000 rev./min, 4° C.); the pellet is resuspended in fresh medium and incubated for a further 2 h. The pellet is then resuspended in 0.9% NaCl solution and the number of cells is adjusted to about 10⁸ CFU/ml using standard curves. The resulting suspension is then diluted with Müller-Hinton broth to about 10⁴ CFU/ml(=inoculum).

Starting from the inoculum, a determination of the number of organisms is carried out by spiralling out (2×0.1 ml) a suitable dilution stage onto CASO agar plates.

Test procedure: Specific concentrations of the potential inhibitors are dispensed into a 96-well microtitre assay plate, wells A1-H1remaining empty. The wells of the microtitre assay plates are inoculated with the adjusted suspension of organisms. Wells A1-H1serve as growth controls. Immediately after inoculation and after incubation of the plates for 24 h and 48 h, they are measured in a plate reader (Biotek EL 311) at 550 nm. From the crude data, the inhibition of bacterial and fungal growth is calculated in percent.

General Synthesis of the Compounds in a 96-well Format (Examples 3-9)

200 μl of a 1M amine solution in dichloromethane, 200 μl of a 1M aldehyde solution in dichloromethane and 1 equivalent of Et₃N are added directly to each well. The reaction mixture is shaken overnight without being covered. The residue formed is taken up in 200 μl of MeOH; 200 μl of 2M TOSMIC solution in methanol. The plate is closed using a Santoprene dimpled mat (Zinsser Analytic GmbH, Frankfurt) and an additional Teflon mat and is screwed tight. The aluminium block is heated at 80° C. for 4 h. The block is then allowed to cool and the reaction vessels are opened with caution.

The solvent is evaporated off overnight. The residue is taken up in 600 μl of ethyl acetate (EA) and 300 μl of water are added. With the aid of a PP plastic mat, the EA phase is shaken three times with 300 μl of water for the purpose of extraction. The aqueous phase is, in each case, drawn off and collected in a further “deep-well” plate. In order to remove the remaining remnants of water, a spatula tip of sodium sulphate is added to the EA phase and shaken. The EA phase is drawn off and the salt is rinsed with 100 μl. Then 2 amounts, each of 100 μl , of 2N hydrochloric acid are added and shaken for the purpose of extraction. The aqueous phase is collected in a further plate. That further plate then contains the purified imidazole derivative, which is in the form of its hydrochloride.
